OK, so am slowling learning baseball and i'm tackling my first excel spreadsheet for Yahoo h2h league.

This is my problem. All the ranking programs don't tell me how the assign weights to their ranking systems for each stat. I have no probs with the single categories like H, R, BB etc but how do i give a weight to AVG, WHIP, etc?

I was thinking that i need to find league averages for each stat and then rate accordingly. i.e. if the MLB league batting average is .270

then a player that hits 270 gets 0, 285 or higher +1, 300 or more +2 315 or more +3 and of course negative as well.

My problem is where do i find league averages for AVG, OBP, SLG, OPS ERA, WHIP and k/9 for 2003?
